This set of more than 430 flash cards offers both review and practice for the AP Computer Science A exam. The cards include string manipulation, list handling, Java keywords, inheritance, and polymorphism. Concepts on the front of each card are defined and explained on the reverse side. Additional exam practice comes from 100 sample problems, with solutions on the reverse side. The cards have a punch hole in one corner that accommodates an enclosed metal key-ring-style card holder, allowing students to arrange the flash cards in any sequence that suits their study needs. Here is a valuable study aid, whether used alone or in tandem with Barron's AP Computer Science A exam review book.
